Abstract
A method and apparatus of a device that transmits a message using a light pattern is described. In an exemplary embodiment, the device receives an indication to transmit a message using the light pattern. In addition, the device activates a flash on the device. The device further encodes the message into instructions for transmitting the light pattern. The device additionally transmits the message using the flash according to the instructions for the light pattern.
Claims20
A non-transitory machine-readable medium having executable instructions to cause one or more processing units to perform a method to receive a message transmitted using a light pattern, the method comprising:
- activating a camera sensor on a first device;
- detecting the light pattern using the camera sensor emanating from a second device using the flash of the second device;
- transforming the light pattern to a message;
- and
- presenting the message on the first device.
A method comprising:
- activating a camera sensor on a first device;
- detecting the light pattern using the camera sensor emanating from a second device using the flash of the second device;
- transforming the light pattern to a message;
- and
- presenting the message on the first device.
A device comprising:
- a camera sensor;
- at least one processor;
- a memory coupled to the processor though a bus;
- and
- a process executed from the memory by the processor that causes the processor to activate the camera sensor on the device, detect the light pattern using the camera sensor emanating from another device using the flash of the another device, transforming the light pattern to a message, and presenting the message on the device.
